FASTENING DEVICE FOR, PAPERS.

Application filed January13, 1926. Serial No. 80,987.

T This invention relates more particularly to A a class of holding devices or clips.

My invention has for its object primarily to provide a fastener adapted to be employed for removably holding together sheets of paper or other material againstaccidental separation and loss for reference thereto as occasion requires, and which is of a form designed to be applied'either to a corner or'to one of the side edges ofthe papers for enabling'the device to be advantageously used to meet various requirements with respect to the related positions of the sheets or to the subject matters thereon.

= The fastener is'made of a plate of pliable sheet metal for being folded to provide two leaf members for receiving therebetween the paper to besecured, and the plate may be formed to provide'the leaf members of ap-' propriate shapes. WVhen the device'is of a typefor being applied to the side edges-of papers, one of the members is provided with a protruding prong for penetrating and for being bent upon the paper and covered by the second" member when also folded upon the paper towardthe first namedleaf memher. 'lVhen the. device is of a form for fastening together the corners of papers, one of theleafmembersis folded to provide a triangular pocket to receive the papers, and one of the walls of the pocket is divided into spaced parts. Protruding from the second wallbetweenthe spaced parts of the first wall is a prong for penetrating and for be- .ing bent upon the paper by contact. of the second leaf member when folded toward the I pocket:

. A furtherobject of the'lnvention is to provide a'fastening device for papers of a simple and eflicient form which may be made in appropriate-sizes and shapes. V

NVith these and other objects in view, the invention will be hereinafter more fully explained with reference to the accompanying drawing forming a partiof'this specification in which similar charactcrsof reference indicate corresponding parts in all the views, and :will then be pointed out in the claims at thewend of the description.

In the drawing, Figure lis a perspective view of one form offaStning device embodying-m-y'invention:

F ig'. '2 is; a fragmentary view showing a number :of papers with thedev-ice in partly folded position for fastening one of the cornersof the papers together.

Fig. 3 isa fragmentary view showing another step in the folding of the device for fastening the papers.

Fig. 4c is a fragmentary view showing the device when completely folded for fastening the corners of the papers. Y

Fig. 5 is a fragmentary view showing the The device is made from a plate of pliable I sheet metal to provide a blank 10 which may be of any suit-ablesize and shape, though the blank. illustrated is formed to provide one end portion of a substantially rectangular shape, as 11, and to provide the other end portion of an" approximately semi-circular shape, as 12. Two spaced parallel ribs or scorings, as 13, 14, be formed in the blank at the intersection of the rectangular end portion .11 with the semi-circular end portion 12 for enabling the blank to be folded to provide a leaf member 15 and a second leaf member 1.6 andfor enabling the part of the blank between the ribs 13,14 to bend in the formation of a groove, as 17 Fig. 7 for receiving the sheets of papers, as "A, when the device is used.

The leaf member 15 is also scored or ribbed, as at'18, 19, from the ends of the rib 13 on converging inclines so that their second ends terminate in spaced relation at the central part of the edge of the leaf member 15 opposite to the-rib13. The portion of the leaf member 15 between the rib 18 and the contiguous corner of the: leaf member provides a flap member 20 of a triangular tit) shape, and the portion of this leaf member between the rib 19 and the adjacent corner of the leaf member provides another flap member 21 also of a triangular shape. As shown,

provided between the 'fiap mem'ber's and'the I i the curved edg-e'12 of the blank, and this leaf member is of a size so that when folded upon the papers toward the leaf member 15 it will engage and bend the prong 23 to overlapping position on the papers as Well as covering the prong for preventing the fingers of the person manipulating the device from being injured by the prong. In order to stiffen the leaf member 16 when made of very thin sheet metal I may provide on the member a number of spaced ribs, as 241,

which extend from the rib 13 to nearly the curved edge of the leaf member for overcoming tendency of the leaf member to curl.

The central rib may be arranged for'serving as a guide 25 by contacting the point of the prong 23 to cause it to properly bend upon the papers.

When the device is used for attaching together the corners of a number of sheets of the papers A, as shown in Figs. 2, 3, 4:, the flap members 20, 21 of the leaf member 15 are flexed right angularly upward in the i direction of the prong 23. The lapping cor- 'ners ofthe sheets of papers are then an, ranged, as indicated in Fig. 2, between the upwardly protruding flap members, and the papersare caused to be penetrated by the prong. The flap members are t-hen folded on the papers toward the prong, as indicated in Fig. 3, and by folding the device on the rib 14: toward the leaf member 16 the papers will also be likewise folded. By pressing the leaf member 16 toward the flap members 20, 21 the prong 23 will be contacted by the guide 25 and bent upon the papers, and the leaf, member16 will cover the prong as well as covering theflap members.

' The device isemployedfor fastening-together one of the side edges of sheets of paper, as shown in Figs. 5, 6, 7, by arranging the papers so that their edges are and way between the ribs 14 and 15 of the device, and the papers are pressed for causing them to be penetrated by the prong. The leaf member 15 will then lie flat upon one face of the papers. The leaf member 16 is then folded over the edges of the papers toward the leafmember 15, and during this movement the guide 25 will engage the prong 23 which in turn will be bent upon the papers forsecuringthem between the leaf members. The prong will also be;oovered by the leafmemberlG to prevent pricking a person ters Patent ing myself thereto, as I'am aware that modifications maybe made therein without de parting from the principle or sacrificing any of the advantages, of this invent-ion, therefore, I reserve to myself the right to make such changes as fairly fallwithin thescope thereof. 1 g

Having thus described my invention, I claim asnew and desire-tosecure by Let- 1. A paper fastenerpcomprising a plate .of
